Teens Accused of Cold-Blooded Killings

In the first case, an Alabama teen, Landon Hudson Durham, 16, is accused of not only stabbing his mother and two brothers to death; police say he actually went to bed, slept the night away, and then went to school the next morning like nothing had happened.

The second case involves a kid whose blood runs even colder. The blood in this teen's veins could be downright frosty.

Police in Grantsville, Utah, a small town just west of Salt Lake City, say Colin "C.J." Haynie "methodically" murdered his mother, brother, and two sisters, then waited for his dad to return home for work.
